How many units of each type should be sold in order to maximize total profit?
A store sells two types of sodas, A and B. The store owner pays $8 and $10 for each one unit of soda A and B respectively. One unit of sodas A yields a profit of $2 while a unit of sodas B yields a profit of $3. The store owner estimates that no more than 2000 sodas will be sold every month and he does not plan to invest more than $20,000 in inventory of these sodas.
How many units of each type of toys should be stocked in order to maximize his monthly total profit?

Estimates are an important part of mathematics. They help to give an approximate idea of a result without having to calculate an exact answer. In mathematics, an estimate is a rough calculation that is not completely accurate, but still provides a general idea of the size, amount, or degree of something. Estimates are very useful in everyday life, as they allow one to make a quick decision without having to go through the time consuming process of calculating an exact answer. Estimating also allows one to make quick predictions, forecast numbers, and plan for future events. Estimating can save time and money and is an essential skill for anyone studying math.
